Circuit breakers, such as the 413-K34-FN2-55A, are designed to protect electrical systems from damage caused by an overload of current. As an important part of any electrical setup, circuit breakers are designed to automatically open the circuit when the current level rises too high for the system to safely handle. This prevents potential damage to the electrical system and its components.

Most circuit breakers utilize a thermal-magnetic mechanism to detect an overcurrent. The thermal-magnetic system, originally invented by Thomas Alva Edison in 1882, utilizes two different parts to detect a surge in current. The first component is a bimetallic strip which detects a rapid increase in temperature and activates the circuit breaker switch. The second component is an electromagnet which is activated when the current passing through it rises to an unsafe level. When the current level is too high, the electromagnet engages, flipping the circuit breaker switch, thus interrupting the circuit flow and preventing further damage.

The 413-K34-FN2-55A is a single pole, thermal-magnetic type circuit breaker. It is designed for use in residential and light commercial applications in 120V and 240V AC branch circuits. The breaker features a snap-acting Trip-Free mechanism, which ensures that the circuit remains open after the overload has been cleared. It is also UL listed and complies with UL489 specification.

In addition to its thermal-magnetic protection, the 413-K34-FN2-55A also offers additional protection against ground fault current. This feature will detect any current imbalance between the phase and the ground wire and automatically open the circuit if the imbalance is too great. This prevents potential ground faults and possible shorts in the circuit.

The 413-K34-FN2-55A is a reliable and cost-effective solution for protecting electrical systems from damage caused by an overcurrent. The combination of thermal-magnetic protection and ground fault current detecting capabilities makes it an ideal choice for residential and light commercial applications.
